Data correlation table main contents on information and video storaging equipment
Video image information Intelligent Recognition
Splicing control module can carry out Intelligent Recognition to the equipment state on video image or parameter, when great amount of images shows simultaneously, helps user to find emphasis rapidly, improves the ease for use of system.
Apparatus for establishing characteristics of image and position feature storehouse.In the linkage control device Installation and Debugging stage, start and build library facility, autoscan video image, intellectual analysis, manual setting, manual confirmation combine, and carry out record to the equipment of required monitoring and the information such as the characteristics of image of state and position feature.Also can start the identification to present image in plant running at any time, increase or edited image feature and position feature storehouse.
The state of equipment is identified, the following recognition strategy of general employing: gather image respectively in each duty of equipment, carry out graphical element analysis, comparing difference, record key element and difference, and the presetting bit etc. of video camera.When needing to identify, carry out retrieval together by this key element, difference, presetting bit and compare.
The peculiar recognition strategy one of energy production conveying equipment: important colour recognition.A lot of equipment has red or green light instruction when opening or closing, certain state when red, green light go out, and each state bright light mode is different, and the brightness change carrying out redness or green in key area is compared, and can reach the object of state recognition.
The peculiar recognition strategy two of energy production conveying equipment: important lines and angle recognition.Need during a lot of equipment operation to arrive ad-hoc location, could normally work.Such as: the electric knife gate of power transmission and distribution, six pivoted arms of three-phase must change into three straight lines and could contact well; If disconnecting link does not contact well, or separation not yet in effect, all major accident may be produced.Splicing control module is six straight line key elements to six of electric knife gate three-phase pivoted arm identifiable design, if these six straight line key elements become three longer straight line key elements, represents that disconnecting link forwards co-bit to; Becoming six parallel straight line key elements, is then that correct separating brake has put in place.After splicing control module identifies this image information, on picture, superpose recognition result in time.
User according to different equipment situations, when edited image feature and position feature storehouse, should choose different recognition strategies, or many strategies combine, to improve the correct recognition rata of system.
Video image information strengthens
Splicing control module on the video images according to the dynamic state of parameters Overlapping display figure arranged, sign flag or word, so that the content of the easier observation video image of user, can strengthen the readability of information.
Set up video image enhancement mode storehouse.In the device Installation and Debugging stage, start and build library facility, autoscan video image, intellectual analysis, manual setting, manual confirmation combine, and carry out record to the equipment of required monitoring and the information such as the characteristics of image of state and position feature; Set the symbol, word and the display mode that need Overlapping display simultaneously.Also can start in plant running and the information superposition of present image is strengthened, increase or edit the symbol or information that need identify and show.
When linkage control device normally runs, coordinated signals module searches data correlation table to the change events occurred, control video camera and turn the presetting bit of specifying, splicing control module is according to the position feature query image enhancement method storehouse of video camera, and the facility information in video image and mode storehouse is compared, determine equipment position in the picture; By the mode of video image enhancement mode lab setting, video information is processed, the figure that dynamic superpose is arranged in video image, symbol and word.
When equipment is moveable, equipment characteristics of image on the video images position and size can change, and the information of superposition also will move with sports equipment on image, keeps the effective mark to equipment.
When camera lens rotates convergent-divergent, the position feature of video camera can pass to splicing control module, and the information of superposition also will move or convergent-divergent with equipment on image, keep the effective mark to equipment.
The present invention compares with usual manner following advantage:
One, the control of energy plant stand video and large screen display control to become data linkage Automatic Positioning Control from manual control.
Event occurs user needs to see video time, native system plays the video of window display equipment needed thereby automatically on splicing large screen, and user is without the need to numerous and diverse operation.
Such as during dispatching of power netwoks person's straighforward operation, if yardman wants the live action image by equipment operated by video-see, because plant stand video monitoring equipment and dispatching automation equipment are respectively in different electrical production network security districts, manual operation video monitoring system on the special purpose computer that yardman needs another video monitoring, and the video camera that will see to be found in thousands of cameras, and clearly must know the accurate location of the equipment that will see, by camera lens convergent-divergent, sense of rotation equipment position.General provincial traffic department is responsible for hundreds of plant stands, and video camera has several thousand, and the equipment that these video cameras will monitor nearly several ten thousand, manual operation is carried out to so a large amount of control points, all too difficulty, do not have practicality to say.The associated picture video intelligent of the equipment that yardman will operate by native system ejects and is presented on splicing large-size screen monitors, does not need yardman to have extra operation, uses easily; And be delivered to large-size screen monitors display be video data, there is not network security risk.
Two, video image intelligent identification, improves energy production security, strengthens the ease for use of user.
Such as: the electric knife gate of power transmission and distribution, six pivoted arms of three-phase must change into three straight lines and could contact well; If disconnecting link does not contact well, or separation not yet in effect, the major accident such as arc discharge, scaling loss disconnecting link may be produced.And traditional equipment state is all by travel switch identification, if six pivoted arms within an ace of do not forward position to, then travel switch may action, causes information errors; If there is part not have action to put in place in addition in three-phase, travel switch detects and cannot find equally.
This generic operation is generally need watch's execute-in-place disconnecting link now, and confirm result, efficiency is low.If adopt Remote operation, then carry out artificial cognition by video image, often need manually repeatedly to adjust video camera, troublesome poeration, easily put in place because operator schemes convenient inspection, cause the accident, therefore the ratio of Remote disconnecting link application is not high.Splicing control module is six straight line key elements to six of electric knife gate three-phase pivoted arm identifiable design, becomes three long straight line key elements, represents that disconnecting link forwards co-bit to; Becoming six parallel straight line key elements, is then that correct separating brake has put in place.Splicing controller superposes recognition result after identifying this image information in time on picture, greatly improves the security of operation.
Three, video image dynamic superpose graphical symbol or Word message, strengthens the readability of information.
Eject on the video image of display when information change, native system superposes related symbol or word automatically, identifies the device location relevant to this data variation information or status information, is strengthened by video image, facilitates user to identify.
The equipment of current straighforward operation can be superposed a frame and label by such as native system, and handled easily person when number of devices is too many at the scene, also very clearly can sees rapidly and need remote-operated equipment; Native system superposes word simultaneously, and identify the title of this equipment, state, handled easily person observes confirmation.
This mode also can effectively prevent maloperation from arriving miscellaneous equipment, if because regulation and controlling of information acquisition module obtains is the telecommand of another equipment, then frame can be added on another equipment, show the number information of another equipment, operator can notice that the operation of controlling oneself may be wrong at once simultaneously.
Four, the equipment failure of original spoken and written languages transmission and record or accident information can be upgraded to visual video image information and record by native system.
Existing system is generally that dispatching automation equipment is with the display of the form of word and preservation data variation information; The some skies of the continual video recording of video monitoring equipment, the time one crosses and automatically covers; Onrelevant between the two.Linkage control device, by the data variation information of written form and relevant video record fragment centralized stores, facilitates user to inquire about.Storage time according to user's requirement, can reach more than 10 years.
Such as have substation transformer equipment lightning fault, originally yardman Xu Deng transformer station person on duty is to field observation situation, then reporting by telephone accident conditions, because the accuracy of individual language performance differs, the information of transmission may exist deviation.Linkage control device, by the original information transmitted by person on duty's spoken word, upgrades to the real time video image information of multiple video cameras splicing large screen directly ejecting display and accident device-dependent; Ageing, the accuracy of information, comprehensive, integrality is better; Yardman can be allowed to make fault handling and isolation fast and accurately, shorten fault handling time, improve power supply reliability.Simultaneously original in the record of textual representation, also bring up to the record that word adds video record.When user inquires about certain accident information, each relevant video recording at that time can be watched simultaneously.
